ROTARY SWING.

SPECIFICATION forming part of Letters Patent No. 340,193, dated April20, 1886.

' Application filed October 7. 1884.

1"0 aZZ whom, it may concern:

Be it known that 1, WILLIAM J. BISHOP, a

citizen of the United States, residing at Baltion with the accomyanyingdrawings, which illustrate what is deemed the best means of carrying theinvention into effect.

Figure 1. is a side view of the swing a d its carriage on a track laidon the ground. Fig. 2 is a top view of one endof the carriage. Fig. 3 isan end elevation of the swing and its carriage.

The letter A designates the seats of the swing. each seat having hangersb, which are pivoted at b to the arms B of a rotary frame. Four arms areshown, but more than f.:lll, or lcss,may be employed. The frame is fixedon a horizontal shaft, 0, whose ends are journaled in bearings 0,thereby enabling the frame and hanging seats to rotate in a verticalplane. The bearings which sustain the rotary frame are supported onstandards H, mounted on a carriage, D, having wheels 6, which traversethe rails ofa track, f. Therotary frame will turn between the standards.This track may be elevated or may lie on sleepers G, placed on theground. \Vhether the track be elevated or not, the rotary swing willmove in a horizontal plane at the same time that the seats are revolvingin a vertical plane. To effect these combined movements simultaneously,a single crank or equivalent driving device on-the carriage is employed,and mechanism connects this driving device both with the carriagerunning-gear and the shaft of the retary swing. The shaft 0 of therotary frame has a driven pulley, k, and a drive-pulley, L, is mountedon a crank-shaft, I, on the car- Serial No. 144,007. (No model.)

riage D. A rope or belt, it, passes over these two pulleys. The shaft onwhich the crank or other driving device is mounted has a cogwheel, (notseen in the drawings, because inclosed in the casing 1),) and saidcog-wheel gears with a similar wheel, q, on the axle r of thecarriage-wheels e. It will be seen that upon turning the crank thecarriage will be moved and the rotary frame turned.

Instead of a crank to be turned by hamlpower, I may use an equivalentdriving device-such as a pulley or cog-gearing-and I may employ steam orother power. The track may extend straight or maybe laid in a circle. Ifstraight, the carriage will pass back and forth; ifin a circle, it willrun continuously in one direction.

Heretofore a toy swing has been made to rotate in a vertical planebetween uprights made fast to an axle, which axle was mounted on twowheels, like a cart, and the whole drawn by a tongue. A frictionalconnection was also made between the said two wheels and the shaft ofthe rotary swing, whereby upon drawing the toy by the tongue the swingwould rotate. I lay no claim to such a device, my invention beingdistinct therefrom.

Having described my invention, I claim and desire to secure by LettersPatent of the United States- The combination of a carriage whollysupported on wheels resting on the track, a horizontal shaft, 0, restingin bearings onthe carriage, a swing-frame supported on the horizontalshaft to rotate in a vertical plane, a pulley attached to the said shaftof the swingframe, a crank-shaft on the carriage provided with a pulley,a cogwheel, q, on the carriageaxle, gearing connecting the saidcrank-shaft and cog-wheel, and a drive-belt, a, connecting the pulley onthe swing-frame shaft with that on the crank-shaft, as set forth.

In testimony whereof I aifix my signature in presence of two witnesses.

\VILTJIAM J. BISHOP.
